Usage: Place for every 50mm pot length 1 - 2 large grians (30mm) or 4 - 8 small grains (10mm) on the soil. The grains may be pushed into the ground a bit. Keep Abrakas moist to get the best result. The granules can also be put in a fertiliser basket with some spagnum moss. Abrakas will be effective for 6 or 7 weeks. Then replace the grains. Apply 4 - 6 times a year to your bonsai.
